In Fig. 6, the door '13 is shown closed in the opening of the door frame11, and the bolt bars 193 and 194 are shown in their laterallyextendedpositions overlapping the door frame keeper wedge bars 182 and184.

In Fig. 7, the door 13 is shown swung to the fully open position, withthe bolt bars 193 and 194 in their laterally retracted positions. Thebolt bar 193 has a longitudinally extending side face 197 which has thesame lateral slope as that of the door case outer side face 195, and inthe retracted position of the bolt bars, the bolt bar side face 197 isaligned with the door case side face 195. Similarly, the bolt bar 194has -a longitudinally extending side face 198 which has the same lateralslope as-that of the door case outer side -face-'1'96,-an'd in '-theretracted position of the bolt bars, the bolt bar side face 198 isaligned with the door case side face 196.

The bolt bars 193 and 194 are formed respectively with co-planar backfaces 199 and 200, opposite inner side faces 201 and 202, and co-planarfront faces 203 and 204. The back faces 199 and 200 are parallel withthe front faces 203 and 204, and the inner side faces 201 and 202 areperpendicular to the front and 'back faces.

The outer front corner of the bolt bar 193 is formed with a front tongue205 and an intermediate groove 206, the tongue and the groove extendinglongitudinally the length of the bolt bar. The tongue 205 extendslaterally outwardly, and the groove-206 opens laterally outwardly.

The door case side member 30, as above stated, has an. inwardly openinggroove 191 formed therein, and is also formed with a laterally inwardlyextending tongue 257 forming one side of the groove 191.

The bolt bar tongue 205 is aligned with and extends into the door caseside member groove 191, and the door case side member tongue 207 isaligned with and extends into the bolt bar groove 206.

Similarly the outer front corner of the bolt bar 194 is formed with afront tongue 208 and an intermediate groove 209, the tongue and thegroove extending longitudinally the length of the bolt bar. The tongue208 extends laterally outwardly, and the groove 209 opens laterallyoutwardly.

The door case side member 31, as above stated, has an inwardly openinggroove 192 formed therein, and is also formed with a laterally inwardlyextending tongue 210 forming one side of the groove 192.

The bolt bar tongue 208 is aligned with and extends into the door caseside member. groove 192, and the door case side member tongue 210 isaligned with and extends into the bolt bar groove 209.

The immediately foregoing details of construction are best shown inFigs. 3, 6, and 7, and in Figs. 12 and 17.

Referring in particular to Figs. 11 to 17, inclusive, and moreparticularly to Figs. 11 and 16, at the lower end of the rear endopening of 6 of the door 13 there is located a laterally extendingelongated spacer bar 211 having a rectangular cross-section and a bottomface 212 aligned with the bottom facei2l3 of the door case bottom member29.

The front face 214 of spacer bar 211 abuts the back face of door casebottom member 29, Fig. 15. The bottom face 213 of the door case bottommember 29, is aligned with the bottom face of the door case side members30 and 31.

The top face ofthe door case top member 28, also is aligned with the topfaces of the door east: side members 30 and 31, Fig. 12.

The spacer "bar 211 also has aback face 215, and an elongated track bar216 has a front face216" abutting the back face 215 of the spacer bar211, the track bar being in side by side alignment with the spacer bar211 and having a length substantially less than the length of the spacerbar. The track bar 216 extends equal distances from opposite sides of avertical medianfplane perpendicular to the back face 27-1 of the doorcase back plate 27, and indicated by the dot-dash line 217 in Figs. 11and 16.

The track bar 216, and the spacer bar 211 have formed therein aplurality of sets of registering bores, each, set including acountersunk bore 218 in the track bar 216 and a bore 219 in the spacerbar 211, and the bores 218 and 219 of each 'set register with aninternally threaded socket 22d formed in the door case bottom member'29. A plurality of cap screws 221 secure the track bar 216 and thespacer bar 211 to the door case back plate 27, each cap screw 221 havinga threaded shank 222 extending through one of the sets ofregisteringbores 218 and 219 and screwed into the registered socket 220, and eachcap screw 221 having a head 223 located in the countersink of theassociated bore 218 and clamping the track bar 216 and spacer bar 211against the door case back plate 27, as shown in Fig. 15.

The track bar 216 has an upper face 224 in the opposite ends of whichthere are formed track grooves 225 and 226. At the lower end of the boltbar 193 there is mounted a U-shaped shaft hanger block 227 havingrearwardly extending legs 228 and 229 which have formed thereinhorizontally aligned bores in which are mounted the ends of a shaft 230.A wheel 231 is located between the block legs 228 and 229, and the wheel231 has a central bore through which the shaft 230 extends.

The Wheel 231 is externally cylindrical and is supported by and rolls onthe track bar 216. As shown, the wheel 231 rolls in and is guided by thetrack groove 225. The load applied to the wheel 231 by the supportedbolt bar 193 is thus eccentric to the axis of rotation of the wheel 231.

At the upper end of the door 1.3, there is located a laterally extendingelongated spacer bar 211 'having a rectangular cross-section and a topface 212' aligned with the top face 213' of the door case topmem'ber'28. The front face 214' of the spacer bar 211' abuts the backface of door case top member 28, Fig. 12. The top face 213' of the doorcase top member28 is aligned with the top faces of the door case sidemembers 30 and 31.

The upper spacer bar 211' also has a back face 215, and an elongatedclamp and stop bar 216' has a front face 217 abutting the back face 215of the spacer bar 211', the clamp and stop bar 216 being inside-by-sicle alignment with the spacer bar 211' and having a lengthsubstantially less than the length of the spacer bar.

The clamp and stop bar 216' and the spacer bar 2.11 are separablysecured to the upper end of the door case back plate 27, by meanssimilar to those above described which separably secure the track bar216 and spacer bar 211 to the door case back plate 27. 7

As best shown in Fig. 12, the upper end of the bolt bar 193 is formedwith a front rabbet notch 193-1, and upper spacer bar ZIP-extends overthe notch 193- 1,

7 and acts as a hold-down for the upper end of the bolt bar 193.

Combined plumbing and moving means are provided for maintaining theeccentrically supported bolt bar 193 in laterally movable positions ineach of which, each of the exterior faces of the bolt bar 193 includingthe side face 201 is plumb or vertical, and the combined plumbing andmoving means being operative to move the bolt bar 193 laterally to itsextended position as shown in Fig. 11, and therefrom to its retractedposition as shown in Fig. 16.

The combined plumbing and moving means is constituted in part by amultiple linkage indicated generally by 232 and including an upper pivotpin mounting block 233-U and a lower pivot pin mounting block 233-L eachbeing secured to the bolt bar 193 and extending from its side face 201towards the median plane 217.

Each of the blocks 233-U and 233-L is of identical construction, and theblock 233-L is described in detail with particular reference to Fig. 14,as follows: The block 233-L has a cross-section which is generally U-shaped, and includes a back web 234 which abuts against the side face201 of the bolt bar 193. Spaced legs 235 and 236 extend laterally fromthe back web, and the legs 235 and 236 have formed therein aligned boreswhich support the ends of a pivot pin 237.

The multiple linkage 232 furthermore includes an upper cross link bar238-U and a lower cross link bar 238-L. The outer en'd of the uppercross link bar 238U is located between the legs of the upper block 233Uand has a bore formed therein through which extends the pin 237 in theupper block. Similarly, the outer end of the lower cross link bar 238-Lis located between the legs of the lower block 233-L and has a boreformed therein through which extends the pin 237 in the lower block.

As parts co-acting with the multiple linkage 232, there are mounted onthe door case back plate 27, a set of upper roller guide blocks 239a and23%, and a set of lower roller guide blocks 240a and 24%. The upperblocks 239a and 23% have, respectively, opposite inner vertical sidefaces 241a and 241b, equally spaced on opposite sides of the medianplane 217 and forming therebetween an upper vertical roller guide groove242.

The lower blocks 240a and 2401) have, respectively, opposite innervertical side faces 243a and 243k equally spaced on opposite side facesof the median plane 217 and forming therebetween a lower vertical rollerguide groove 244. In abutment with the lower ends of the blocks 240a and24011, there is secured to the door case back plate 27 a roller stopblock 245.

On the outer end of each of the link bars 238-U and 238L, there isconstructed a clevis 246 including an outer leg 247 and an inner leg 248having aligned bores formed therein, and upper portions of a pin 249 arelocated in the bores of the clevis legs 247 and 248 and secured in theclevis as by an upper arcuate securing plate 250 separable connected onthe outer face of the outer clevis leg 247 and engaging an outwardlyopening groove in the upper end of the pin 249 extending above the upperclevis leg 247.-

The lower end of the pin- 249 extends below the lower clevis leg 248 andhas a journal and thrust cup 251 secured thereon, and a roller 252 isjournalled on the cup 251 and rolls between the guide block side facesfor the particular upper or lower roller. The bottom of each of theupper and lower grooves 242 and 244 formed by the upper and lower rollerguide blocks, serves as a slide bearing for the bottom circular thrustface of the particular cup 251 operating in the particular groove.

The multiple linkage 232 furthermore includes an upper connecting lin'kbar 253, the upper end of which is located between the upper clevis legs247 and 248, and has a boreformed therein through which extends theupper portion of the pin 249.

Referring in particular to Figs. 27 and 28, and again to Figs. 11 and16, substantially at the center horizontal axis of the door indicated bythe dot-dash line 254 in Fig. 28, there is mounted a stub shaft 255having an inner externally threaded end 256 screwed into an internallythreaded socket formed in the door case back plate 27. The shaft 255furthermore includes an intermediate annular shoulder 257 which seatsagainst the outer face 27-1 of the back plate 27. The shaft 255 alsomounts on its outer end, needle bearings 258 which mount a gear wheel259.

From the outer face of the gear wheel 259, there protrudes a pilot boss260 having an externally cylindric surface concentric with the axis 254,and a crank disk 261 has a central cylindrical opening 262 formedtherein which fits on the pilot boss 260, the inner face of the disk 261abutting the outer face of the gear wheel 259, and means being providedwhich secure the disk 261 to the gear wheel 259.

From the upper side of the disk 261, there extends outwardly an uppercrank pin 263, and the lower end of the upper connecting link bar 253has a bore formed therein which fits on the upper crank pin 263.

As above stated, the lower cross link bar 238L also has a clevis 246constructed on its outer end and mounting a clevis pin 249 on the innerend of which there is mounted a journal and thrust cup 251 journalling aroller 252 which rolls in the lower groove 244.

A lower connecting link bar 264 has its lower end located between thelegs of the lower clevis 246 and formed with a bore through whichextends the outer portion of the lower clevis pin 249.

The crank disk 261 also mounts a lower crank pin 265, and the upper endof the lower connecting link bar 264 is formed with a bore which fits onthe lower crank pin 265.

The multiple linkage 232 and associated parts as so far described,constitute an independent and complete combined plumbing and movingmeans operatively associated with the vertical bolt bar 193, andactuable by reverse quarter rotations of the crank disk 261 to move thebolt bar 193 laterally back and forth between the positions shown inFigs. 11 and 16.

At the lower end of the bolt bar 194, there is mounted a U-shaped shafthanger block 227 which is identical in construction with the block 227but reversed sideways. The block 227' mounts a shaft 230 and a wheel 231which is supported by and rolls on the track bar 216. As shown the wheel231' rolls in and is guided by the track groove 226. The load applied tothe wheel 231 by the supported bolt bar 194 is thus eccentric to theaxis of rotation of the wheel 231.

As best shown in Fig. 11, the upper end of the bolt bar 194 is formedwith a front rabbet notch 1944, and upper spacer bar 211 extends overthe notch 194-1, and acts as a hold-down for the upper end of the boltbar 194.

Combined plumbing and moving means are provided for maintaining theeccentrically supported bolt bar 194 in laterally movable positions ineach of which each of the exterior faces of the bolt bar 194 includingthe side face 202 is plumb or vertical, and the combined plumbing andmoving means being operative to move the bolt bar 194 laterally to itsextended position as shown in Fig. 11, and therefrom to its retractedposition as shown in Fig. 16.

The combined plumbing and moving means for the bolt bar 194 includeslinkage parts connected with parts of the multiple linkage 232, asfollows: An upper pivot pin mounting block 233'U and a lower pivot pinmounting block 233L are secured to the bolt bar 194 and extend from itsside face 202 towards the median plane 217.

Each of the blocks 233'-U and 233'L are identical in construction withthe block 233-U and 233-L, but reversed sideways.

Each block 233'-U and 233L supports a pin 237.

An upper cross link bar 238-U has its outer end lo cated between thelegs'of "the upper block '233U and 'has-abore formed-thereinthroug'hwhich-extends the pin 237 in the upper block. The 'inner end of theupper cross linkbar 238-U is formedas a clevis 238'-1,tl1e *legsof'which fit between the legs of theclevis 246 of the 'upper cross linkbar 238-1]. The legs of the clevis *238-"1have formedtherein'alignedbores whiehregister with the aligned bores of the upperclevis 246. .The upper endofthe upper connecting link bar 253'fitsb'etween the legs of the upper clevis 238-1 and its bore is alignedwith the bores of'th'e legs'of the upper clevises 246 and 2 38' 1, andfthe upperpivot pm 249 extends through all of the alignedbores.

Similarly, a lower'cross'link bar 238'-L hasits outer end locatedbetween the "legs of the lower block 233'L and has a bore formedthereinthrough which extends the pin 237'inthe lower block. The innerend of the lower cross "link bar23'8-L is formed as a clevis 238"1, thelegs ofwhich fit between the legs of 'theclevis 246 of the lower crosslink bar238L. The legs of the clevis 238'1 ofthe lower cross link bar238'L have formedtherein aligned bores which register with the alignedbores of the" lower clevis 246. The lower end of the lower connectinglink bar 264 .fits between the legs of the lower clevis 238 1, and itsbore is aligned with the bores of the legs of'the lower clevises 246 and238-1, and the'lower pivot pin 249 extends through all of the alignedbores.

Theinclusionof the crank disk 261- and the upper and lower connectinglink bars 253 and 264 in the linkage 232 constitutesa-pai'riof co-acting'linkageshaving common actuating parts for simultaneously plumbing andmoving the bolt bars 193 and 194.

In the improved vault door construction 10, after the boltbars 19'3and194 have been moved laterally to the extended positions shown in Figs.3, 6, 11, and 12, the vaultdoor 131's bolted in the opening of the doorframe 1 1,and'the two st'op mechanisms indicated generally by 2-70 and271, respectively, are provided for blocking operation'of the plumbingand moving means associated with the bolt bars 193 and 194 to move thebolt bars from the "extended position to the retracted position.

The 'stop mechanism 270 is operatively mounted on the back face 27-1ofthe door case back plate 27 and islocated above the stub shaft 255 andbelow the upper cross link 'bars 238-U and 238' U. Most of the parts ofthestopme'chanism 270 are locatedbetween the median plane 217 and thebolt bar 194. The stop mechanism 270is=time lock controlled by a timelock indicated generally by 272 which is mounted on the back face 27-1of the door case backplate 27 and is located above the stub shaft 255and below the upper cross link bar 238-U and between the median plane217 and the boltbar 193.

The "stop mechanism 270includes among other parts, a 'plunger 273extending horizontally from a horizontal cross bar 274 mounted forhorizontal movement on the door case back plate 27; At its end adjacentthe time lock 272, thecross bar 274 has mounted'thereon a rearwardlyextendinglug 275, which isspring' pressed towards the time lock 272. Thetime lock 272 includes a stop arm 276 whichin-the locked position of theparts of the time lock as shown in Fig. 1 1, is in a position blockingmovement ofthe plunger 273 and cross 'bar 274 towards the time lock.When the time lock parts have moved to the unlocked position shown inFig. 16, the stop arm 276 has been moved to a position permittingmovement of the plunger 273 into the case of the time lock.

Referring particularly to Figs. 11, 16, and 19 to 23, inclusive, the lug275' is formed with a counter bored aperture 277, a swing bar 278extending generally u'pwardly-and-downwardly,'has a pivot mounting means279 intermediate its ends, the pivot mounting "means being secured onandextendingoutwardly from'the doorcase back plate 27. At the lower 'endof'th'eswin'g bar 278, there is secured an'end'pi'ece 280 having anapertu're 281 formed therein which is aligned withthe aperture 277 inthe1u'g275.

A bolt and nut'set 282 connect'the endpiece280 and the lug 275,thesha'nk of 't-heb'olt extending through the aligned apertures 277 and281, and a helical compression spring283'isinterposed and'reactsbetween'the end piece 280"and th'eYlu'g275, and as shown the spring'283is wound around the shank of the bolt of the set'282.

The cross bar 274 hasformed'therein a pairof aligned laterally spacedelongated horizontal slots "284, andv a roller 285 is located in eachslot 284, each roller 285 being stud'mounted "on the door case backplate "27. 7

As best'shownin Fig-20, the upper roller. guide block 23%. ha formedtherein a laterally extending forwardly opening.rectangular'groove 286which with the back face 27 1 of the" plate 27, 'forms a guide slot. Astop bar 287 extends horizontally through and is slidable -in the 'guideslot.

*Between'the stop bar 287 and the crossbar 274, there is secured'to andextends rearwardly from the back plate 27, a'pivotal mounting means 288,and a lever bar 289 is pivotally mounted intermediate its ends on thepivotal mounting means 288. The lever bar 289 extends generally upwardlyand downwardly, and the upper ;-end of the lever'ba'r 289 base slotandpin connection 290 with the outer end of the. stop'bar 2 87, and the"lower end of "the leverhar289has a slot and pin connection 291 withaniintermediate.portion of the cross bar 274.

The upper connectinglink bar "253 has an outer side face with an angledportion 292. As best shown-in Fig. 23, a formed double angled platemember 293 ineludes an angled outer leg'294 separably secured to thelink bar "253 above its angled s'ide face portion 292. The doubleangledplate member "293 also includes 'anangled side leg 295 spaced fromthe angled side face portion 292 of the link bar 253, and formingtherewith aforwardly opening angled groove 296 at the rear of theswingbar 278. A roller 297 rolls in the groove 296 and has a stud shaftmounting 298 on the upper end of the swing bar 278. p

The time-lock controlled upper stop-mechanism 270 as above describedin-detail, operates as follows: When the door is inthe closed.positionas shown in Fig. 11, and the bolt work has been operated toextend the bolt bars 193 and 194 to the extended door bolting position,the stop bar 287 is located in extended position across the upper groove242, preventing full downward movement of the upper journal and thrustcup 251, and thus preventing operation .\of the bolt work to retract thebolt bars. In this locked and stopped position of the-bolt work, thestop mechanism .270 cannot operate to withdraw the stop bar 287 from thegroove 242, until the time lock 272 has operated to drop the stop arm276 from obstructing .position with respect to the plunger 273. Whenthis occurs, the spring 'pressed plunger 273 may enter the housing ofthe time lock.

The other-lower stop mechanism 271 is controlled by two combinationlocks 300 and 301. Mounting means for the locks 300 and30-1consist of alock mounting plate 302 spaced rearwardly from the door case back plate27 and parallel thereto, and sets of spacer and connector means eachincluding a cap screw 303 and a tube spacer 304, each spacer 304 beinginterposedbetween theplates 302 and 27, and the bore of each'spacerregistering with abore in the plate 302 and an internally threaded borein the plate 27, and the shank of-each cap screw 303 extending through aset of the registering 11 bores and being screwed in the threaded bore,and the head of each cap screw clamping against the back face of theplate 302.
